Filed: 1982-08-23
Abstract: PURPOSE:To obtain a digital subtraction system in which the contrast resolution is improved with a fluorescent board with less deterioration in contrast, by exposing intermittently X-rays with a high-strength intensity and recording a picture so as to attain the luminance intensifying effect. CONSTITUTION:An X-ray high voltage device 12 is controlled via an interface 10 by operating an operation panel 10 and X-rays with a high-strength intensity are exposed from an X-ray tube 13 to an objective 14. The X-ray transmission image is converted into an optical image at the fluorescent board 15, inputted to an image pickup tube 16, where the image is converted into a video signal and given to a video processor 20. The signal is converted logarithmically at a logarithmic converter 21 to grasp the ratio of the amplitude of signals of the objective, allowing to obtain a sharp blood vein image. The image is digitized at an AD converter 22, a signal before the infusion of contrast medium is stored in a frame memory 24 and a signal after the infusion is stored in a memory 25, and the subtraction of them forms a picture corresponding to the part of the contrast medium. The contrast is emphasized at an enhancement circuit 26 and given to a monitor TV 31 via a DA converter 27.

Inventor: HAGINO HIDEO
IPC: H01M8/06
Filed: 1987-06-11
Abstract: PURPOSE:To promote the generation of fuel gas to be supplied to a fuel cell from a reforming device and to smoothly excite the electricity generating system by interposing a burner fuel reforming device reforming a part of mixed liquid of methanol and water only when the burner is ignited, in the burner fuel supply passage of a methanol reforming device. CONSTITUTION:In this method, a part of mixed liquid of methanol and water is reformed into H2 and CO through the small-sized burner fuel reforming device 1 only when the burner of methanol reforming device RF is ignited. Consequently, the ignition time is shortened by about one minute in comparison with about 10-15 minutes of ordinary method even though in the environment below the freezing point because of the existence of combustible gas. Thus, the generation of fuel gas to be supplied to the fuel cell FC from the reforming device RF is promoted by the sure ignition and stable burning of burner with the result that the excitation of power generating system is swiftly and smoothly carried out.

IPC: G11B5/127
Filed: 1999-05-26
Abstract: PROBLEM TO BE SOLVED: To make it possible to adequately process a winding groove which affects the depth accuracy of a magnetic gap. SOLUTION: When the winding groove 108 is processed at a core 102A of the magnetic head chip, processing is executed by grinding using two kinds of grinding wheels dividedly to a depth determining region 108A which is a portion facing the magnetic gap 106 of the winding groove 108 and a winding region 108B which is another portion. First, the processing of the winding region 108B of the winding groove 108 involves the execution of grooving of a square shape by the grinding wheel 230 having a square cross section. The processing determines the processing conditions attaching greater importance to productivity (processing rate and cost). Next, the processing of the depth determining region l08A of the winding groove 108 involves the execution of grooving by the grinding wheel 240 having a V-shaped cross section.  The grinding wheel having a fine grain size and a high autogenous effect is used in this processing as the processing is directly related to depth accuracy.

Title: Recoil counterrecoil and control method thereof and shock absorber
Inventor: YAMAMOTO KAZUHIRO
IPC: F16F9/53
Filed: 1994-06-28
Abstract: PURPOSE:To control the movement of a gun barrel and a breech ring freely by making variable the viscosity of a magnetic fluid which cooperates with a recoil piston in a recoil apparatus installed to the breech ring or a reciprocating body by means of an electromagnet. CONSTITUTION:When a recoil piston rod 8 mounted to a breech ring 1 and a recoil piston moves back, the strength of a magnetic field which an electromagnet 25 generates by a control current from a current controller 30 due to narrow flow passages of an oil passage 6a and a valve 21 is preliminarily controlled in conformity with the positions of the breech ring 1 and viscosity resistance of a magnetic fluid 12 is controlled. Due to this, the movement of the recoil piston 7 is braked so that a sun barrel 2 and the breech ring 1 may be moved slowly. When the force of recoil is eliminated and the sun barrel 2 and the breech ring 1 are forced to move back, the breech ring 1 and the gun barrel 2 move forward and return to their original positions. It is, therefore, possible to change the viscosity of the magnetic fluid 12 freely and adjust a recoil motion freely by controlling the electric current to the electromagnet 25 while detecting the position of the breech ring by means of a position detector 32, not based on the definite viscosity of the coil.
